Abstract

Abstract:

This paper mainly includes: (1) Agreeing with the viewpoint of Shanmugam (2016), i. e.,the term “seismites” proposed by Seilacher(1969) is problematic. It is not the beds with soft-sediment deformation structures (SSDS) and it is without evidence of earthquake, therefore it should be negated. (2)Disagreeing with the viewpoint of Gong Yiming(1987,1988), i. e., the term “seismite” should not be translated into “zhenjiyan” (震积岩), but it should be translated into “dizhenyan” (地震岩). (3) SSDS are of multiple origins. The beds with SSDS induced by earthquake can be named “seismites” while the beds with SSDS not induced by earthquake cannot be named “seismites”. (4) In a seismically active area, it is not sure that all SSDS are induced by earthquake. (5) In a river valley of the Garhwal Himalaya, northern India, a seismically active area, the SSDS occurred immediately in 2013 flood sediments is an irrefutable case study which is not induced by earthquake, because from 2013 till today earthquake never occurred in this area. This case study should be paid attention to and thought deeply.

Key words: seismites, dizhenyan, zhenjiyan, soft-sediment deformation structures, non-seismites
